Home from the relay and top end off the motor, broke timing chain and got 4 valves. I guess 500 lift springs with .470 lift intake and .430 lift exhaust is too much for a 75 Z1 stock timing chain. Parts getting ordered today and should have everything cleaned up and ready to go back together by the time the parts get here.

Yeah the HD Tsubaki chain would have been a better choice during the build... :blush:

Same time, could have been a lot worse than 4 valves and a banged piston dome... Engines can be rebuilt and you obviously have the skills... ;)

Not to mention while riding an engine lockup/crash & burn, not good, makes a truly bad day... :pinch:

Stock 75 Z1 cases, never been apart. I just done a top end on it and really not disappointed with the failure other than the time it chose to go. Kinda impressive and a kudo's for the guys that designed them, 37 year old motor and who knows just how hard of life it may have led before I got it. But anyway, an update.
Head is tore down, cleaned up and waiting on the valves. Should have the cases out and stripped down before nightfall. Clean them tomorrow and get started Installing trans and what ever else I can before parts get here. May even get the crank welded or just put a 1000 crank in it that is allready welded to save some time. If time allows I'll throw a fresh coat of paint on it to look like new again. Pics may be few, I hate this new camera but I'll do what I can when I take breaks. :laugh:

Oh it hasn't, it's my play toy and I play hard. I'm really surprised it didn't let go sooner. I'm on my 2nd front tire and 3rd back if that's any indication of it's life with me. I agree on the redline on a stock motor, they don't make the power up there and stock valve springs don't like it much past. The head was built to be bullit proof, shim under buckets, .500 lift springs, titanium retainers and stainless valves. I ran .430 lift exhaust and .470 lift intake and it made power up high, came on like a 2 stroke at 7500 and it spent quite a bit of time up there. :woohoo:

Okay, got a little free time, waiting on parts. Just a little update but I will tell you now, the bolt in monoshock and motor swapping ain't friendly. Yeah, I know, I'm telling you where my parts come up short. Had to unbolt the shock, take the right side shock mount out because it is part of the upper right hand back motor mount. Not overwhelming but none the less, had to do it.
Started lapping valves and setting stem heights so I should have the exhaust side done tomorrow evening. Then it's do the intakes, get the timing chain in and hopefully, fired by friday evening.

Also head is cleaned up and I just touched lapped the seats with good valves to make sure I didn't screw a seat up, all seems good and ready to lap and reassemble. Turns out the valves I had were stock and this is 1mm over so I'm real glad I ordered the exhaust too.

Also got a chance to clean the chassis up a little with the motor out.

Got all the parts in and they were the right parts! Exhaust side of head done, bottom end done and layed in the chassis. I should be able to have the cases bolted in and the the top end buttoned up tomorrow. Game plan is to have it ready to fire by Saturday afternoon, provided I can get out of work. If not, I'm going to be one tired person Sunday for the Turkey Run meet up.
